Federal Communications Commission Washington, DC 20554 International Bureau August 26, 2011 Verizon Business RTE 120 494 Roxbury Pond Rd. Andover, Me 042167 Re: Email, Paul Blais, FCC 22 August 2011, attached. Dear Messrs. Hoff, Gonzalez, Burrows, and Ms. Kao: The Commission has recently received a request from Canada that indicated it would like to deploy terrestrial stations (FS) that operate in the 3650—3700 MHz frequency band, within a 150km perimeter of your FSS earth stations, call signs E0O00306, E0O00700, KA349, KA386, WA20, and E930190 located in Andover, Me. FCC docket 05—56 Report and Order established a 150 km circular protection zone for Grandfathered FSS earth stations, such as yours, under a streamlined licensing approach for fixed stations. Canada proposes using FCC 05—56 Report and Order, Appendix D methodology, to reduce the protection zone for Canadian applicants at your Andover, Me, site(s). Our Systems Analysis Branch (SAB) of the Satellite Division, in the International Bureau, has reviewed the Canadian proposal in detail and believes that its proposal is technically sound, and would decrease frequency coordination demands and expenses on your facility(ies). Our review included development of a Microsoft Excel based protection calculator that has been forwarded to by the referenced email. The calculator calculates protection zones based on the formula described in appendix D of the FCC 05— 56 Report and Order, and is inclusive of the changes defined in Memorandum Opinion and Order FCC 05—184. The tool was used to calculate the proposed new protection zone

about your Andover, Me, earth stations and plot it on "Google earth." A graph of the protection zone shape and orientation are also plotted on the Excel worksheet , "Visual Output," in the Excel file forwarded by email and a printout for elevation angle = 5° is attached. Overlaid protection zone plots for 5,10,15,20, 35, and 38.5 antenna elevation angles were also compiled and are provided for your review. The Commission seeks Verizon concurrence to reduce the protection zone for your Andover, Me., site. In view of the fact that deployment of broadband FS systems is of national interest and is being pursued by Canada, as well. It is beneficial for economies of both nations to support each other. We would appreciate your cooperation in this matter. We request that your response to this proposal be received by this agency within 30 days of the date of this letter. A non—response will be considered as your concurrence with this proposal. Please forward all of your related correspondence to address(ees), as listed here. Postal delivery: Marlene H.
